The Ruta10 is near the ocean, and there are in the area some little fishermen villages, most of them built around lighthouses. Cabo Polonio is located in a "national park" area or "protected area". Population is 200 people aprox. There are no roads to arrive! You must have a 4x4 or horses to cross the 4 km sand tracks from the paved route to the village. They don't have electricity, water, etc, however, I think this is the most peaceful place I know.
